(-3,-4) i want to say not sure
28! hope this helps, you just plug in 4 for x, and then multiply by two.
Answer:
Y=3x+2, Y= -3x-2
Step-by-step explanation:
If you need a consistent (parallel) line you must have very similar equations, with only positives and negatives being changed. If it's Y=3x+2, only the 2 is changed from negative to positive changing the lines position. If it's Y= -3x-2 then the X value is moved to a different coordinate and the -2 keeps the change.
Hope this helps and please critique what I've done if im wrong.
let y = x^2
4y^2 -21y + 20 = 0
solve for y
then substitute back in to get x
Y= 1x + 2
Use the formula y=mx+b when trying to do things like this.
Y intercept form is when your line intersects through the y axis, and this is also your b. M is your slope.
